I'm working on a patch to make it act that way.  I've got some issues
yet to fix with named arguments (which seem rather undertested BTW,
since the patch is passing check-world even though I know it will
crash instantly on cases with CALL+named-args+out-only-args).

Before I spend too much time on it though, I wanted to mention that
it includes undoing 2453ea142's decision to include OUT arguments
in pg_proc.proargtypes for procedures (but not for any other kind of
routine).  I thought that was a terrible decision and I'm very happy
to revert it, but is anyone likely to complain loudly?
